Capacity Programming / Schematic Design
Confidential Client Programming / Schematic Design for Process & General Exhaust Systems
Problem:
The Process Exhaust Systems use, code compliance, and facility upgrades required to support the Client’s current, Future Planned “Pipeline Tools”, and additional growth for a new pilot line to be installed at the Client’s facility located in Maricopa County in the City of Chandler, Arizona.
The intent is to review the current exhaust systems (General Exhaust / Acid Exhaust / Solvent Exhaust). Diamondback Design Group (DDG) will provide the Client with Programming / Schematic Design services to understand the current system capacity of the General Exhaust (GE), Acid Exhaust (AE), and Solvent Exhaust (SE) Systems on the Client’s Chandler Campus. DDG scope is to review the data, include client provided input for future growth and then provide proposed new exhaust fan selections where required in order long lead equipment can be procured in a timely manner. DDG will also provide a schematic level design based on the agreed upon Basis of Design post programming effort.
All existing exhaust fans operated via Variable Frequency Drives (VFDs), allowing for variable-speed control in response to system demand. As part of this scope, Fan RPM (FRPM) values will be reviewed and documented to capture the actual operating conditions of each fan. This information will help:
- Confirm whether existing fans are operating efficiently within their performance curves
- Support accurate selection or modification of new / existing fans
- Ensure compatibility with system static pressure requirements and control strategies
This analysis will inform the overall exhaust system design and ensure the proposed solutions align with both current performance and projected growth requirements.
Solution:
Diamondback Design Group worked with the local equipment suppliers, on-site trade partners, Test and Balance contractors, and the Client’s team to produce a meaningful solution to the exhaust system short falls. Diamondback was able to successfully provide a final Programming Document and Schematic Design package that allowed the Client and their trade partners to purchase long lead equipment needed to meet the new pilot line tool installs within 4-weeks. Diamondback took ownership of Fab tool exhaust data, and POC Pre-assignment matrix; and Gap analysis efforts to quickly close any open issues to keep the project on schedule.
“I wanted to express my sincere appreciation for putting this schematic design together. It was very well laid out, and I particularly noted the inclusion of all the necessary symbols and information, which is extremely helpful. The placement of the main components was also well done and contributed to the clarity of the design. I really appreciate your efforts here and wanted to extend a job well done to you!”
